THOMAS FOSTER WHITE, OF SALEM, KANSAS.

WRENCH.

SPECIFICATION forming part of Letters Patent No. 297,209, dated April22, 1884.

Application filed September 8, 1883. (No model.)

To ILZZ wiz/0772, it 77u14/ concern:

Be it known that l', THOMAS F. WHi'TE, a citizen of the United States,residing. at Salem, in the county of Jewell and State of Kansas, haveinvented a new and useful Wrench, of which the following is aspecification, reference being had to the accompanying drawings.

This invention relates to wrenches5and it has for its lobject to providea device which will be readily convertible into a nut or pipe wrench ata moments notice.

To 'this end :it consists in certain details of construction andcombination of parts, as hereinater set forth, and particularly pointedout in the claims.

In the accompanying drawings, Figure lis a perspective view of my deviceadj usted as a nut-wrench. Fig. 2 is a similar View when adjusted as apipe-wrench, and Fig. 3 is a longitudinal section of Fig. 1.

The same lettersrefer to correspondingparts in the several figures.

For purposes of description, the end of the wrench farthest from thehandle is the forward end, and the side on which the jaws are the frontside.

Referring to the drawings, A designates the shank of an ordinary wrench,provided at the forward end with stationary jaw B and at the oppositeend with a handle, C.

D designates the sliding jaw, provided with an opening, ci, for thepassage of the shank, and having a rearward extension, E, to which ispivoted orjointed a forward extension, F, of a sliding sleeve, G, thelatter sliding on the shank, and arranged to slide the jaw D toward oraway from the stationary jaw. A ange, H, projects downwardly from therear end of the sleeve G, and is formed with a groove, i, in its innerface, while a worm-wheel, I, longitudinally movable on the shank,engages with the groove in the iiangc, so as to cause the longitudinalmovement of the sliding jaw carrying the sleeve. The circumference ofthe lworm-wheel is provided with serrations or with a milled edge, inorder to provide for the ready manipulation of said wheel. It will beseen that the extension F of the sleeve is bifurcatcd or slotted toreceive extension E of 5o the sliding jaw, said extension E readilytting within and working in the slot, so that the conversion from a nutto a pipe wrench can be easily performed. A. spring, J, is secured tothe front or upper face of shank A, andbears against the inner faceofthe sliding jaw, so as to press said jaw outward when working on pipeor round iron, and apointed screw or rod, K, works through au opening,Z, in the side of the slidingjaw, so as to engage with a longitudinalgroove, L, formed on the side of shank A. This pointed screw or rodguides the sliding jaw when used as a nutwrench, and also serves as ameans for adj ustment of the wrench from a wrench for nuts to a wrenchfor working on pipes or round iron. The inner faces of the jaws D B areserrated, milled, or provided with teeth to engage with the pipe or nutsin turning, said teeth or serrations extending bin opposite directionson each jaw.

The operation of my invention'can be readily understood from theforegoing description, taken in connection with the annexed drawings.

When used as a nut-wrench, the screw Kis engaged with grooveL and guidesthe sliding jaw and sleeve in its movements, the manipulation ofworm-wheel I causing the sleeve to slide upon the shank, the saidsleeve, by means of :its connection with the sliding jaw, causing thelatter to move longitudinally on the shank. Thus the turning of theworm-wheel regulate the distance between the jaws B D.

To change the nut wrench into a pipewrench, the screw or rod K is firstwithdrawn from slot L, and 'since the lower or sliding jaw is jointed tothe extension of the sleeve, and is, furthermore, forced toward thefront side of the wrench by spring J, said sliding jaw will be thrown tothe position shown in Fig. 2, and can thenbe used to turn pipes or roundiron in making joints or like work.

When used as apipe-wrench, the operation IOO to mechanics, sinceheretofore two different wrenches have been used to perform thefunctions-of my single device. I thereby avoid the cost of the otherwrench, while the great convenience arising from its use will beappreciated by all.

. It is apparent that numerous modifications can be resorted to in theforegoing without de parting from the spirit or scope of my invention.

Having described my invention, I claim as newl. In a wrench, the shankprovided with a slot or groove in its side, in combination with thesliding jaw pivoted or jointed to a sliding sleeve, and a pointed screwor rod working through the side of the jaw and engaging with the slot orgroove, as and for the purpose set forth.

2. In a wrench, the shank A, carrying stationary jaw B, and providedwith a longitudinal groove in its side, in combination with the slidingjaw pivoted or jointed to a sliding sleeve, and having a pointed screwor rod en` gaging with the longitudinal groove, and a spring secured tothe shank and bearing against the inner face of the sliding jaw,substantially as and for the purpose set forth.

3. In a wrench, the shank A. provided with a longitudinal groove or slotin its side, in combination with the sliding jaw formed with a rearwardextension, a sleeve provided with a forward extension, which is pivotedor jointed to the said rearward extension, a pointed screw or rodworking through the sliding jaw and engaging with the groove in theshank, and a spring bearing against the inner face of the sliding jaw,as and for the purpose set forth.

In testimony that I claim the foregoing as my own I have hereto affixedmy signature in 4o presence of two witnesses.
